MedfordTrees Mini-Forest: The Livable Lab
Medford’s Mini-Forest is Underway: Highlights from Our Community Meeting February 3rd
On February 3, TreesMedford hosted a community meeting to share plans for Medford’s first mini-forest pilot at Tufts Park, and to invite residents into the work. The turnout, questions, and constructive discussion made it a clear success. We’re grateful to everyone who showed up in person and online to learn, share concerns, and help shape the project.
This mini-forest is a small-footprint, high-impact native planting designed to grow quickly, support biodiversity, and strengthen climate resilience, while serving as a hands-on community stewardship project.
Who we are and why we’re doing this
TreesMedford is a volunteer-run 501(c)(3) focused on expanding Medford’s urban tree canopy and restoring native habitat. We do this through public education, advocacy, watering support for newly planted street trees, events, and collaborative projects with the City of Medford. We’re always looking for more volunteers to help with this work.
At the meeting, we connected the mini-forest project to a reality many residents already feel: Medford is getting hotter, and canopy loss makes that worse. Trees are one of the most effective local tools we have to reduce heat, improve air quality, manage stormwater, and make neighborhoods healthier and more livable.
What is a mini-forest?
A mini-forest (often called “Miyawaki-style”) is a small, densely planted woodland built using native trees and shrubs. Unlike traditional street-tree spacing, mini-forests are planted tightly so plants compete for light and close canopy faster. That faster canopy closure helps suppress weeds, create habitat sooner, and reduce long-term maintenance over time.
At our meeting, habitat restoration specialist Dan Bender explained the basic principles:
Plant the species you’d find in a mature forest, not just the early colonizers.
Plant densely, so the forest structure develops quickly.
Put heavy emphasis on site preparation (decompacting soil, adding organic material, and building soil biology).
Expect the most hands-on stewardship in the first 1–3 years, with maintenance dropping significantly once the planting is established and canopy closes.
Just as important: mini-forests are built with locally native species that are adapted to our region and provide far more ecological value for insects, birds, and other wildlife than many non-native or invasive trees.
Why Tufts Park?
This pilot is funded by a $10,000 Medford Community Fund grant and is designed intentionally as a proof-of-concept: a small installation (about 100 square meters) that demonstrates what mini-forests can do in an urban park.
Tufts Park was chosen through a community-driven process. TreesMedford asked residents to suggest locations, received roughly 30 candidate sites, and then visited and scored them. The goal was to identify a site that could support a healthy planting while also maximizing public visibility and community learning opportunities.
During the meeting we also acknowledged something many people care about: Tufts Park is used in many ways, including an area nearby where off-leash dogs often play. This mini-forest is not intended to “take over the park.” The goal is coexistence: a protected young planting that will grow into a thriving pocket of habitat while the park remains a shared space for everyone.
What we heard at the meeting (and how we’re responding)
One of the strongest outcomes of the meeting was the quality of the questions. Residents asked smart, practical thing, exactly what we want to surface early.
Here are a few themes that came up:
Fencing and access
To protect young plants during establishment, the mini-forest will be fenced temporarily and include at least one gate for access. The intent is to remove the fence once the planting is established, though we’ll continue to evaluate what’s best for the long-term health of the forest and compatibility with park use.
Construction and park access
The park will not be “shut down” for the project. Planting and installation will be planned to keep the space accessible, and we’ll sequence any equipment use with safety in mind—especially given the park’s heavy use.
What if we find rubble or poor soil?
Urban parks can hide surprises beneath the surface. If excavation reveals rubble or concrete, we may shift the planting footprint within the park to a better micro-location. Soil testing and site prep planning are part of the next phase.
Long-term maintenance
This is a stewardship project. TreesMedford expects to support maintenance for the foreseeable future, with the goal that the mini-forest becomes low-maintenance after establishment and aligns with normal park upkeep patterns over time.
Costs and comparisons to other towns
Mini-forests are still relatively new in the region, so long-term cost patterns are limited, but we’re learning from nearby examples and local expertise. This pilot is designed to be achievable, well-supported, and replicable.
Timeline: what happens next
We’re moving from planning into implementation. Our current expectations:
Site prep and layout refinement (including aesthetics and design details) will continue in the coming months.
Planting is targeted for fall (roughly September–October; exact dates will be announced).
Volunteer recruitment will ramp up as planting approaches, and we’ll share ways to help through the TreesMedford website, email list, and a sign-up form.
How you can get involved
This project only works if it’s truly community-supported. There are multiple ways to participate:
Join a planting day
Help with mulching and watering during establishment
Assist with weeding and invasive monitoring
Support education and outreach (signage, tours, event help)
Bring a school group or youth organization into stewardship activities
If you’d like to help, keep an eye on upcoming announcements and sign up through our volunteer form when we post planting-day details.
Thank you
We want to thank everyone who attended and helped make the meeting productive and encouraging. The mini-forest pilot is an opportunity to do something tangible and hopeful: build a small native woodland in a place the community already loves—and learn together how to grow more of them across Medford.
We’ll share updates as we finalize the site plan and planting schedule. If you have questions or want to get involved, reach out to TreesMedford or join our mailing list for updates.

Proof of Concept Planning at Tufts Park
Planning has begun for a small proof-of-concept (POC) mini-forest at Tufts Park, in partnership with the City. This first site is designed to be a visible, learn-by-doing demonstration that we can replicate across Medford, showing how dense native plantings can bring shade, habitat, and long-term ecological value to public spaces.
TreesMedford is piloting a dense native mini-forest to help restore Medford’s tree canopy in one of our hotter, more paved neighborhoods. This “livable lab” will test new ways of planting and caring for trees, while creating shade, habitat, and a place to learn about urban ecology.
What Is a Mini-Forest
Accelerated Growth (Miyawaki Method):
Dense planting (3–5 seedlings per m²) mimics natural forest succession.
Trees and shrubs grow up to 10× faster than conventional plantings.
Achieves a self-sustaining ecosystem in ~20 years (vs. 100+ years naturally).
Carbon Sequestration & Climate Resilience:
Rapid biomass growth means higher rates of carbon capture in early decades.
Helps offset municipal greenhouse gas emissions and supports climate goals.
Improves local resilience by reducing urban heat-island effect.
Native Planting Focus:
Uses local native species adapted to soil, climate, and wildlife.
Reduces long-term maintenance, irrigation, and chemical input needs.
Builds ecological integrity by avoiding invasive or non-adapted species.
Wildlife & Keystone Species Benefits:
Keystone native species (e.g., oaks, willows, cherries) support hundreds of insect and bird species.
Provides critical pollinator habitat, bird nesting, and food webs.
Enhances urban biodiversity, supporting ecological balance.
Community & Municipal Benefits:
Small footprint (as little as 100 m²) makes it viable on under-used city parcels.
Provides visible greening, shade, and air quality improvements.
Engages community volunteers, schools, and civic groups in planting and stewardship.
Thank you for helping us find mini-forest locations!
Thank you to everyone who filled out the TreesMedford mini-forest survey. Your ideas helped us map potential sites across the city where more shade, habitat, and tree canopy are needed. Every suggested site was added to a shared map so we could see the full range of possibilities in one place.
From that city-wide map, we narrowed down the list by:
Focusing on heat island neighborhoods with higher temperatures, including parts of South Medford, Glenwood, and Wellington.
Selecting sites on city-owned land where a dense native planting could realistically move forward and fit with existing park uses.
Scoring each site for water access, visibility, site condition, invasive species, and heat-island impact.
From this process, we identified ten especially promising locations. Our first mini-forest will be a small proof-of-concept at one of these sites so we can test the approach, learn what works best, and apply those lessons to future projects.

Mini-Forest Proof of Concept (PoC)
TreesMedford is piloting a dense native mini-forest on city land in one of the ‘heat island’ neighborhoods of Glenwood, Wellington, or South Medford to help demonstrate Medford’s historical native tree canopy in one of our hotter, more paved neighborhoods. This “livable lab” will test new ways of planting and caring for trees, while creating shade, habitat, and a place to learn about urban ecology.
Key Points of the PoC
A 100 m² plot (10×10 m) planted at 3 plants/m² = ≈ 300 plants gives dense canopy & understory cover from early on.
Demonstrates rapid ecosystem establishment using Miyawaki method: layered planting of trees + understory shrubs + groundcover accelerates growth, soil stabilization, carbon capture.
Allows testing of survival & growth rates in local urban soil / light / moisture conditions, helping to refine species selection & planting technique.
Serves as a biodiversity hub: supports native insects, birds, small mammals; possibly serves as a demonstration / education site for the public.
Shows cost / maintenance needs (watering, fencing, protection) in local context; gives solid data for budgeting.
Community project in heat island neighborhood, high visibility.
Helps illustrate methods and species to address Medford tree canopy deficiencies (invasive replacement, drought tolerance, under-represented species).
Plant Selection with Intention.
While Medford historically falls into a number of natural communities, most of the sites recommended by the community that fall in the heat island neighborhoods are either Dry, Rich Oak Forest / Woodland, Oak–Hickory Forest, or Sugar Maple–Oak–Hickory Forest. With this in mind, the mini-forest subcommittee has assembled a list of target species from the appropriate natural communities.
